Sly router + Adguard home

[FlyingDragonz]

Hi all, new here. Found a few threads that talked about Adguard home and as this is a UK forum, should make it easier.
So, simply put, has anybody got a Sly router (sr203) and AGH to play together.
I'm trying and losing my rag trying to setup and run AGH on my first newly built NAS/Home lab with Truenas OS.
Sly being sly, things are locked down so cannot use DNS, thus has to be DHCP but I'm struggling.
I'm stuck with the whole static ip address prompt. My Truenas is setup with a static address (which I believe is the meaning).
I cannot only disable the Sly DHCP via the config edit and upload but everything just tanks.
I then have no DHCP in AGH (which I do enable), sly router is rebooted but nothing.
I have read about people people buying new routers to replace the sly one, but that adds more expense, plus the whole option 61 thing some discuss is a required, plus I use the landline phone connection so theres that too.

Anybody had any succcess, some tricks or advice. I've tried pi-hole too, same block?

Please & Thanks

I admit I almost skipped over this post, as reading 'Sly' so many times made my eyeballs bleed. You can express your disdain with reason, but we're not 12. I'm still not entirely sure what is your issue. You have AGH running on TrueNAS. I assume Scale/CE rather than Core? How is it running on the host? Is it sharing TrueNAS' LAN IP or does it have its own?

Not very clear. I assume your issue is setting the Sky router's DHCP server's DNS setting for local clients? Not sure what that has to do with requiring a static IP, unfortunately. You've written a wall of words and not produced much by meaningful information or clear questioning. Please try again. Post exactly what hardware and software you're running, what steps you've taken so far, your objective (DHCP on AGH or SKy router? Using AGH's IP as DNS for DHCP clients? etc), what the error and/or issue is, and list any questions thereafter. You'll likely garner more replies and help that way. Welcome to the forum.

In the less legitimate corners of the internet, it’s customary to avoid using the providers name, so Sky became Sly and Virgin became Vermin etc. It comes from a belief that not using the provider name will fly under the radar.

Yes, I know how monumentally dumb that sounds at this point, but way, way, way back, it likely had some merit.

Yeah mate, I did know that but it's 2025 and it just reads a bit... Well. Let's see what OP comes back with.

That's quite a word salad there! Saying you can't use DNS so have to use DHCP makes no sense. You writing router 'just tanks' give no insight at all into helping others diagnose the problem.

Why does the provider name need to fly under the radar?

My face hurts.
I think Adguard is asking for a static but you don't know what to give it? It would be a different IP to your TrueNAS one, maybe then you can enable dhcp in Adguard and disable on the CPE?

Can you run your next post through AI before posting please? Use the prompt "Make this readable by normal people".

Screenshots may help us understand better. In theory you should be able to disable DHCP on your router and then enable it in AGH instead if for some reason the router doesn't simply let you pick a custom DNS. The static IP part doesn't make much sense from your post.

Have you made sure any Advanced features are turned on?

Where is AGH hosted?

Apologies all, after post op I've been on some strong pain killers which clouds my thoughts due to sedation feeling but equally, I don't think my questioning/query was so incomprehensible albeit missing some information. ai....
Anyway, to the matter at hand. As I'm totally perplexed, hence my reason for asking as I've followed guides and videos as best as I can.
I don't come from a world of IT, but I'm willing and have learn't slowly to get my homelab running.

I am indeed running Truenas CE and this is what AGH is hosted on. It's a mini ITX intel cpu board with 32GB ram, so far hosting immich, jellyfin, home assistant.
In theory yes, I should be able to simply disable DHCP when ready but thats the issue, firstly the ISP supplied router does not allow custom DNS to be set, secondly the DHCP does not disable easily hence needing to edit the backup config.

From the AGH side, in the DHCP setup menu, I filled in the network details, range, ports as directed.

I'm comfused in the sequence of when to disable one dhcp and enable another. So, I take a stab by disabling router first and reboot (this is done by applying the edited backup coonfig, where the state of TRUE was changed to FALSE in the enable DHCP section).
When trying to enable AGH DHCP I get errors/prompts "AdGuard Home failed to determine if this network interface is configured using a static IP address. Please set a static IP address manually".

This is the information I can supply, hope it has some clarity. Thanks

I promise you it was. I hope you feel better!

A much clearer post, thanks. We only want to help you, and until we knew what you're asking nobody could. I wasn't being picky with you when I asked for clarity. It's much easier to avoid XY problems and actually help when you say clearly and simply what you're trying to achieve, before you say what you've done so far to get there.

You do need to disable the DHCP server on the Sky router in order to run a DHCP server on another device. Unfortunately, as far as I can see it's not possible to fully disable DHCP on the SR203. Your post suggests you tried to restore a config to the router with the DHCP server manually set to disabled, but you weren't successful? That being the case, it's not impossible to circumvent (you could set the Sky router to only manage a single address, or block its DHCP discover/offer/broadcast packets using its firewall if it lets you), but it's far from ideal. Can you not just use your own router and bypass using the Sky junk entirely?

Assuming you can disable or bypass the DHCP server on the Sky router, on the AGH side it checks for a static IP in its own host machine's network config. I assume TrueNAS has a static IP set in its configuration? Did you do this manually (/etc/network/interfaces or /etc/systemd/network/eth0.network or whatever), or via its GUI? Does AGH share and see this address, and is that the server listen address set in AGH's config?

Provided that's all true (static IP on TrueNAS/AGH, AGH set to use it) you can ignore any warnings about a static IP. Once you've set the local network parameters in Settings > DHCP settings > DHCP IPv4 settings, you should be able to enable the DHCP server using the button at the top of the page. If not, click 'Check for DHCP servers' a couple of times, and then try again (ignoring the warnings/errors). Worst case, you can set it up in the AdGuardHome.yaml config file and restart the service.
